Heart Failure Early Symptoms and Signs
Heart failure occurs when the heart muscle is not able to function in a manner that can sufficiently supply the body with oxygen. Congestive heart failure is the failure of the heart muscle to maintain the circulation, leading to a backup of blood in the veins that causes:
- swelling (particularly in the lower parts of the body);
- shortness of breath is another common symptom of congestive heart failure that occurs due to fluid buildup in the lungs; and
- fatigue and a decreased capacity to exercise are other symptoms that commonly result from heart failure.
Early symptoms and signs may not be apparent, and symptoms may develop only after the condition has progressed over time.
